|comment:||This review after my second experience with STF. First i bought when i have A100 and sold it after some week experience because on that moment it was too hard to me focus properly without confirmation. Some later i bought STF again and now much more positive experience, but in all i get only 10% sharp images.|
STF very very special lens. I use it rare, mostly in portrait shooting and sometimes to shoot beauty of nature near macro (flavour, leaves...).
Bokeh is awesome. There are no any other lens that can produce bokeh to compare. Lens is sharp from wide open. And 95% photos i made on STF take from F2.8(T4.5). I think that STF@T4.5 sharper than 85za@F2 and comparable with email@example.com
In bokeh i found many CA (bokeh CA in photozone.de terms).
not fast (T4.5) 135mm lens is not very useful on cropped sensors. I have 15 minutes experience with STF on A900 with M-type screen and it was much more versatile.
On my own A700 for portrait shooting from 85za, 135za, 135STF personally i prefer 85/1.4 lens.
The only minus with STF on my experience is the focus ring. It have small (for manual focus only lens) control angles. i try some M42 lens, macro lens, all typically have angle at ~180-270 degrees, while STF only ~120. STF exceptionally hardly use STF to shoot on distance longer than 3 meters, while (for example) 135/3.5 Takumar was ok at distance to 10.
